Abstract

A magazine for a nail-driving tool, which may be pneumatically powered or combustion-powered, is arranged to store a plurality of plural nail strips in side-by-side relationship. A spring-biased mechanism is used to bias the stored strips toward a side rail. Being movable along a frame between an advanced position and a retracted position, a feeding member in the retracted position engages the shank of an endmost nail of the stored strip nearest to the side rail. A negator spring mechanism biasing the feeding member toward the advanced position includes a leaf spring arranged to be longitudinally pulled between the nail heads of the stored ship nearest to the side rail and the nail heads of the next strip when the feeding member is moved from the advanced position into the retracted position. The feeding member has a wedging portion arranged to push between some of the nail shanks of the stored strip nearest to the side rail of the magazine and some of the nail shanks of the next strip and to lead the leaf spring when moved from the advanced position into the retracted position and a rail-engaging portion arranged to push between the side rail and some of the nail shanks nearest to the side rail when moved similarly. In an operative position, in which it can be releasably latched, a biasing member bears against the nearest strip. A floor member can be adjustably positioned. When latched, the biasing member latches the floor.

Dependent claims

A magazine, for use with a nail-driving tool adapted to receive at least one nail strip comprising a plurality of collated nails and to drive said nails individually and successively from said nail strip, for storing a plurality of said nail strips in a side-by-side relationship with respect to one another so that each stored nail strip has a nail defining a leading end of said nail strip and a nail defining a trailing end of said nail strip, said magazine being elongate, having an outlet end, an opposite end, and a side rail along one side of said magazine, said outlet end of said magazine having an outlet through which the stored strip disposed nearest to said side rail of said magazine is feedable, and wherein each nail of each nail strip stored within said magazine has a head an shank, said magazine comprising:

a frame;
means for biasing said stored strips of nails toward said side rail of said magazine;
a feeding member movable along said frame between an advanced position near said outlet end of said magazine and a retracted position near said opposite end of said magazine, said feeding member having a nail-engaging portion for engaging said nail defining said trailing end of said stored nail strip disposed nearest to said side rail of said magazine when said feeding member is released from said retracted position, after having been moved to said retracted position, so as to feed said nail strip, having said engaged nail, toward said outlet of said magazine when said feeding member is moved from said retracted position toward said advanced position;
and
means comprising a leaf spring for biasing said feeding member toward said advanced position, said leaf spring having a leading end secured to said frame at a position near said outlet end of said magazine, a trailing end secured to said feeding member and movable along with said feeding member, said leaf spring being disposed so as to uncoil as said feeding member is moved toward said retracted position, to recoil as said feeding member is moved toward said advanced position, and to be longitudinally interposed between said stored nail strip disposed nearest to said side rail of said magazine and the next nail strip stored within said magazine when said feeding member is moved from said advanced position to said retracted position as well as when said feeding member is moved from said retracted position to said advanced position.
